如何在PHP中的字符串中找到单词的其余部分？

Question

Let's say I have a page I want to scrape for words with "ice" in them, how can I do this easily? I see a lot of scrapers breaking things down into source code, but I don't need this. I just need something that searches through the plain text on the webpage.

Edit: I basically need something to search for .jpeg and find the entire file name. (it is in plain text on the website, not hidden in a tag)

Answer 1

Anything that matches the following is a word with ice in it:

/(\w*)ice(\w*)/i

(Do note that \w matches 0-9 and _ too. The following might give better results: /\b.*?ice\b.*?/i)

---

UPDATE
To match file names (must not contain whitespace):

/\S+\.jpeg/i

Example:

<?php
$str = 'Picture of me: 238484534.jpeg and someone else img-of-someone.jpeg here';
$cnt = preg_match_all('/\S+\.jpeg/i', $str, $matches);
print_r($matches);
